• TTY Resolution in Xubuntu 9.10

  - by Zurahn

  I've exhausted my ability to search through Google for this, so I'm giving it a go here. What I'm trying to do is increase the resolution (or decrease the font size) in the TTY terminals. Xubuntu 9.10 uses GRUB2, and everywhere I can find directs me to edit the /etc/default/grub File in order to add vga=XXX to the GRUB_CMDLINE_LINUX value, and this simply doesn't work. Out of endless fiddling with the file, nothing ever seems to change. On my Netbook running an earlier version, I had success with this command dpkg-reconfigure console-setup But once again it yields no change. Got any ideas?

• Safely adding SSH users to pfSense

  - by Goyuix

  I would like to add a user for myself to login via SSH to a pfSense box. I don't want to just blindly go through the adduser command and inadvertently break something / open a vulnerability somewhere though. Looking at the config page in the WebUI: I can't find where to add users or to specify their keys. What is the right way to add users that can use SSH? Can I also safely use the AllowUsers directive to keep tighter control of those allowed to login via SSH? Bonus: I would also like to disable root from being able to login via SSH. I can see the option PermitRootLogin in the /etc/ssh/sshd_config file, though I don't necessarily want to modify it directly as I could potentially lose those changes with updates/patches or changes through the WebUI. Thoughts?

• sharepoint 2007 access denied when accessing user profiles via ssp

  - by user22215

  Guys I have a really strange problem in regards to sharepoint mysites today I go into user profiles and properties in order to setup a property all of a sudden I get access denied. First off I know that I'm logged in with the correct account after the access denied I decided to click on personalization services and permissions I than get An unhandled exception occurred in the user interface.Exception Information: Cannot complete this action. I'm not seeing anything in the server application logs either. So have any of you guys seen this before is there some kind of way to grant a user account the manage profiles right permission using stsadm. BTW all other fucntions of the ssp are working fine so my question is if the user profiles and my sites of a ssp tanks how do you repair that portion of the ssp? BTW the user accounts that I'm using are site collection owners and also they have full control at the web application level. I actually ran across this interesting post but this does not really help my problem. http://blog.tylerholmes.com/2008/09/access-denied-for-site-collection.html

• Routing all Traffic through OpenVPN Tunnel

  - by Filip Ekberg

  I have installed OpenVPN server on Archlinux and am now using OpenVPN GUI on Windows 7, I can talk to other computers connected through the VPN but I have not yet figured out how to route all traffic through the tunnel. How do I do this? I figured I need to do it with route ( cmd command ) but I think i need some pointers here. I've followed the OpenVPN HowTo on the matter but that doesn't work, it simply doesn't push the "force the client to go through this gateway"-option. And changing from OpenVPN to a PPTP / IPSec alternative is not an option at the moment.

• SQL Server crashes when remote query fails

  - by Hemanshu Bhojak

  Setup: I have a linked server setup on SQL Server 2005 which is pointing to an Oracle DB. The linked server has RPC enabled. Problem: When a query throws an exception on the remote server (Oracle DB) the SQL Server instance crashes. The logs say that the crash was due to some problem with the RPC call. Is there a way in which I can prevent the entire server to collapse but also use RPC over my linked server. EDIT: Event Log SQL Server is terminating because of fatal exception c0000005. This error may be caused by an unhandled Win32 or C++ exception, or by an access violation encountered during exception handling. Check the SQL error log for any related stack dumps or messages. This exception forces SQL Server to shutdown. To recover from this error, restart the server (unless SQLAgent is configured to auto restart). For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

• What is a ‘best practice’ backup plan for a website?

  - by HollerTrain

  I have a website which is very large and has a large user-base. I am trying to think of a 'best practice' way to create a back up or mirror website, so if something happens on domain.com, I can quickly point the site to backup.domain.com via 401 redirect. This would give me time to troubleshoot domain.com while everyone is viewing backup.domain.com and not knowing the difference. Is my method the ideal method, or have you enacted better methods to creating a backup site? I don't want to have the site go down and then get yelled at every minute while I'm trying to fix it. Ideally I would just 'flip the switch' and it would redirect the user to a backup. Any insight would be greatly appreciated.

• SQL Server 2008 to Sybase Linked Server (x64) -- Provider and permissions issues

  - by Cory Larson

  Good morning, We're testing a new SQL Server 2008 setup (64-bit) and one of our requirements was to get a linked server up and talking to a Sybase database. We've successfully done so using Sybase's 64-bit 15.5 drivers, however I can't expand the catalog list from a remote machine (connecting to the '08 box with SSMS) without having my network account being added as an Administrator on the actual box and then using Windows Authentication to connect to the server instance. This is going to be problematic when we go live. Has anybody experienced this, or have any input on the permissions in SQL Server 2008 with regards to linked servers? If I remove my network account from the Administrators group, the big error I'm getting is a 'Msg 7302, Level 16, State 1, Line 41' with a description something like "Cannot create an instance of OLE DB provider "ASEOLEDB" for linked server "", and all research points to permissions issues. Thoughts? This document talks about DCOM configuration and permissions, but we've tried all of it with no luck. Thanks

• windows server 2008 web edition cant change permissions

  - by minus4

  hi there, Im used to using windows server 2003 but decided to get a Vista web edition for IIS7 and to run our MVC applications on. I have installed copSSH that i use for SFTP, and when i upload my files i am unable to change persmissions or take ownership or anything when logged in as an administrator. when i try to go to permissions i get: The permissions on uploads are incorrectly ordered, which may cause some entries to be ineffective. and all permissions are the grayed out. i have tried to use icacls to reset ownership and also tried to give myself full control through icacls however all attempts are met with a access is denied message and failed processing 669 files. all i wish to do is set up write and delete permissions on an upload folder for a CMS systems admin area, but i am a week into looking into this and i am still no wiser. Please could someone give some sound advice so i can get this running smooth thanks p.s i have added the copSSH notes as i think that when i SFTP the files to the server, this may somehow have some involvement in messing up permissions

• How do I set up a public server on a network?

  - by tyjkenn

  I am trying to set up a personal cloud server with OwnCloud on Ubuntu. LAMP is all set up. I was able to access it using the external IP address when I connected it directly to the modem, but what if I what if I want my server to share a LAN? I still want it accessible over the internet, but then if I go to the IP address from a web browser, it just tries to log into to router admin tools. The internal IP address works across the LAN, but I want to be able to access it from anywhere. This may be simple and I may be over-thinking it, but how do access my server? The router I am using is ASUS WL-520GU.

• Open vSwitch and Xen Private Networks

  - by Joe

  I've read about the possibilities of using Open vSwitch with Xen to route traffic between domUs on multiple physical hosts. I'd like to be able to group the multiple domUs I have spread out across multiple physical hosts into a number of private networks. However, I've found no documentation on how to integrate Open vSwitch with Xen (rather than XenServer) and am unsure how I should go about doing so and then creating the private networks described. As you might have gathered then - from research I think Open vSwitch can do what I need it to, but I just can't find anything giving me a push in the right direction of how to actually use it to do so! This may well be because Open vSwitch is quite new (version 1.0 released on May 17). Any pointers in the right direction would be much appreciated!

• Mixing different generations of ATi video cards

  - by middaparka

  I'm heading in the direction of a three monitor set up and hence suspect I need to go the dual video card route. At the moment, I've a Radeon X1900GT driving two 19" monitors which I'd like to keep and augment with something like a Radeon 5570 which would drive a 22" display. As such, I'm just wondering how Catalyst will cope with this configuration and whether there are any other issues that I'm likely to encounter. In terms of the obvious, my motherboard has two PCI-E slots and my power supply has two video card power connectors, so I'm hopefully covered from that side of things. Thanks in advance.

• How can I get Virtual Server 2005 R2 running on Windows Server 2008 R2?

  - by Bret Fisher

  For various reasons (old VT-less hardware, and .vhd support) we need to still run Virtual Server 2005 R2. It's just for lab/demo work but we'd like to run the host on the newest Windows OS possible. It's documented and at least partially supported to run the old Virtual Server 2005 R2 SP1 on Windows Server 2008 (non-R2). I've done that before. I'm wondering if anyone has gotten the scenario in the title above to work. This post says it's possible but has anyone here actually done it before I go through that process: http://blogs.infosupport.com/blogs/ericd/archive/2009/08/31/running-virtual-server-2005-r2-sp1-on-windows-server-2008-r2.aspx

• Rails3 environment running very slow on Windows XP, Ubuntu 9.04, Ubuntu 9.10

  - by bergyman

  I've tried all three (granted the Ubuntu versions were via VirtualBox with XP as a host, but I gave the images all the available RAM my system has). Loading the rails environment is taking 30-60 seconds. rails console, rake test:units - anything that requires rails to load up. And not just on the first go - every time. I've even used autotest to see if it helps with execution time for unit tests, but it doesn't. Any time I change one test, it still takes 30 seconds to load them, and then about 4 seconds to execute. Has anyone else come across this issue? Has anyone figured out any way to fix this?

• Supplementary Developer Laptop

  - by David Smith

  I'm looking to buy a laptop with the following specs for a developer. The goal will be to have a development machine supplementing the devs desktop. During work hours the dev will be on a beefy desktop. For working while on the go: trains, client sites, code camps, it would be nice to have a machine which can run Visual Studio 2008 without needing to remote desktop into their primary machine. What do you think is the lowest cost laptop meeting this need? Here are the specs I have in mind: SSD drive 64GB-doesn't need to be huge, most data is stored on servers. Will need to fit Windows 7, IIS, SQL Server, and Visual Studio 2010. RAM-3GB processor =Pentium Core 2 duo Screen size = 14 inches. OS doesn't matter. It will be paved with Windows 7 Ultimate optical drive omitted would be a plus. weight and battery life aren't so important because the machine will be plugged in almost all the time.

• PHP Configuration file won’t load IIS7 x64

  - by Martin Murphy

  using Fast CGI I can't get it to read the php.ini file. See my phpinfo below. System Windows NT WIN-PAFTBLXQWYW 6.0 build 6001 Build Date Mar 5 2009 19:43:24 Configure Command cscript /nologo configure.js "--enable-snapshot-build" "--enable-debug-pack" "--with-snapshot-template=d:\php-sdk\snap_5_2\vc6\x86\template" "--with-php-build=d:\php-sdk\snap_5_2\vc6\x86\php_build" "--disable-zts" "--disable-isapi" "--disable-nsapi" "--with-pdo-oci=D:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8=D:\php-sdk\oracle\instantclient10\sdk,shared" "--enable-htscanner=shared" Server API CGI/FastCGI Virtual Directory Support disabled Configuration File (php.ini) Path C:\Windows Loaded Configuration File (none) Scan this dir for additional .ini files (none) My php.ini file is residing in both my c:\php and my c:\windows I've made sure it has read permissions in both places from network service. I've added various registry settings, Environment Variables and followed multiple tutorials found on the web and no dice as of yet. Rebooted after each. My original install was using MS "Web Platform Installer" however I have since rebooted. Any ideas on where to go from here would be most welcome.

• SquidGuard and Active Directory groups

  - by Massimo

  I'm configuring a Linux proxy with Squid and SquidGuard to filter Internet traffic. I know how to authenticate users against Active Directory in Squid, and then how to filter access for users using SquidGuard. The question: how to use Active Directory groups in SquidGuard instead of plain user names? My goal is to be able to configure rules like "members of this group can go anywhere" or "members of this group can only visit certain sites". I know SquidGuard can't manage group membership directly, but it can do LDAP searches on its own; but the syntax to look up wheter a user is member of a given group seems to be quite cryptic, and I couldn't find any good documentation around.

• Git - post-receive hook with git pull "Failed to find a valid git directory"

  - by ludicco

  It's very weird but when setting a git repository and creating a post-receive hook with: echo "--initializing hook--" cd ~/websites/testing echo "--prepare update--" git pull echo "--update completed--" the hook runs indeed, but it never manage to run git pull properly: 6bfa32c..71c3d2a master -> master --initializing hook-- --prepare update-- fatal: Not a git repository: '.' Failed to find a valid git directory. --update completed-- so I'm asking myself now, how it's possible to make the hook update the clone with post-receive? in this case the user running the processes is the same, and its everything inside the user folder so I really don't understand...because if if I go manually into cd ~/websites/testing git pull it works without any problem... any help on that would be pretty much appreciated Thanks a lot

• Linode - Centos 5.5 -

  - by Marcus West

  Hi, I rather foolishly undertook to install a control panel on a Linode. I opted to use CentOs 5.5 (either ordinary or 64 bit) but I am like a monkey playing a reward game... I have some idea of what I am doing, but not enough.... In certain areas I am hopeless....do I install Webmin/virtualmin, or ISP Config..... ISP Config 2 or 3? I would employ someone to help, but how do i find the right person? Where can i learn the ropes on all this? There seems to be no systematic training, and even when I try to research college courses in the UK, I am none the wiser as to where I could go to learn how to run a Linux server..... Has anyone any pointers? Right now I am looking at th esecurity aspects of the server.....rkhunter , denyhosts etc... Any advice on installing and maintaining these things? Cheers marcus

• Lock down a site using Forms Auth in IIS7 with Windows Auth

  - by Josh

  I have an ASP.NET MVC 1.0 application that uses Forms Authentication. We are using Windows Server 2008. I need to lock down the site so that only certain users (in AD Groups) can access the site. Unfortunately, though, when I set the site to not allow anon users and use windows authentication, due to the integration of the site and IIS, it shows the user as signed in as their domain account, instead of allowing them to sign in through Forms Auth. So, I need a mixed mode authentication. I need the site to be only accessible through windows auth, without anon users, but once you are in, it needs to use forms auth only. How would I go about doing this the right way?

• Redirect as a backup trick? w/o modifying DNS?

  - by acidzombie24

  I specifically looked up how to do something like this ( Can you set a backup ip for your server in DNS? ) and the answer basically was you can't. If i say specify 2 ip addresses could i somehow use a HTTP response header to ignore it temporary (say 5mins) and go to the other IP address? Or maybe i can play dead however i'm unsure how to play dead using nginx. I then would like to be available after my box notice the other box is down and be some kind of readonly server. I'm sure something like this has been implemented i am just wondering how i might implement it with 2 boxes. I'm sure it isn't very difficult? How might i redirect traffic from a backup box to my main server without modifying the DNS?

• Automatic subdomain wildcard for DHCP-DDNS additions?

  - by Igor Clark

  I'm running dhcp-4.0.2 server and bind-9.6.1-P3. When a new Mac OSX DHCP client with the name "harry" connects to the network, the DHCP server gives it a lease, and adds appropriate A & PTR records via DDNS. This works fine; harry.my.domain points to (e.g.) 192.168.1.3, the Mac client knows that its name is harry.my.domain, 192.168.1.3 points back to harry.my.domain, and all that is great. Now I want *.harry.my.domain to resolve to 192.168.1.3, and I don't want to have to go in and add wildcard records into zone files. I want the Mac to connect to the network, and have the hostname and wildcard subdomain resolve to the IP address it's been given. Is there a way to do this? Thanks!

• Backing up Information Store - Recovering to Different Information Store / RSG

  - by Kip

  Hi All, I have a question on a situation, that hasn't yet arrisen but I wondered the possibilities and how we go about it. Currently we backup our Exchange 2003 Cluster with Backup exec. Currently it is set to backup the Microsoft Information Store on that server and all of the Mailbox Stores beneath it. We have previously used this in conjunction with a recovery storage group on the same server to recover lost mailboxes. However, due to space constrictions on that server ( a seperate issue that is being addressed in the very near future but outside of the scope of this question) we now don't have enough space on that server to do a recovery storage group type restore. Is it possible, to restore an information store, to a different server in the same administrative group (ie first)? By that I mean we have the following: Server1 | First Storage Group | Mailbox Store1/2/3 Could Mailbox Store 1 be restored to: Server2 | First Storage Group | Recovery Storage Group Both servers are under the same Administrative Group Currently for whatever reason ( mainly time) the mailboxes are not being backed up individually. Regards Kip

• NGinx Best Practices

  - by The Pixel Developer

  What best practices do you use while using NGinx? try_files in Subdirectory Credits go to Igor for helping me with this one. location /wordpress { try_files $uri $uri/ @wordpress; } location @wordpress { fastcgi_pass 127.0.0.1:9000; fastcgi_split_path_info ^(/wordpress)(/.*)$; fastcgi_param SCRIPT_FILENAME /var/www/wordpress/index.php; fastcgi_param PATH_INFO $fastcgi_path_info; } Normally PATH_INFO would include the "/wordpress", so we use the "split_path_info" command to grab the part of the URI after "/wordpress". This allows us to wordpress with and without the index.php file.

• Good book for a software developer doing part-time (Linux) system administration work

  - by Tony Meyer

  In many smaller organisations, developers often end up doing some system administration work (for obvious reasons). A lot of the time, they have great developer skills, but few system administration skills (perhaps all self-taught), and so have to learn as they go, which is fairly inefficient. Are there canonical (or simply great) books that would help in this situation? More advanced than just using a shell (presumably a developer can do that), but not aimed at someone that hopes to spend many years doing this work. Ideally, something fairly generic (although specific to a distribution would be OK), covering databases, networking, general maintenance, etc, not just one specific task. For the most part, I'm interested in shell-based work (i.e. no GUI installed), although if there's something outstanding I'm missing, please point it out. (As an analogy, replace "system administration" with C, and I'd want K&R, with C++ and I'd want Meyers' "Effective C++").

• ISA forms authentication problems after installing moss sp2

  - by user22215

  Guys I have a problem that's flared back up after installing WSS and MOSS service pack 2. The problem centers around the users being prompted to enter credentials when interacting with office documents. This problem came up before and I was able to go into ISA server and configure a persistent cookie on the web listener. As we all know when configuring a cookie you have two options use only on private computers or use on all computers. If I select use on all computers I can't even log in to Sharepoint from the forms page however if I select use only on private computer I'm able to log in and also I don't get prompted when opening office documents. So I would like to ask has something changed with Sharepoint service pack 2 because that’s the only change that’s been made to my environment.
